Mobile phones

A large percentage of eddy-current inspections are conducted in the field, away from the home base and often in remote or inaccessible locations. Using local telephone lines or mobile phone lines would allow the inspector to beam his data back to the office. In this way highly qualified personnel can be consulted when problems or difficult to interpret results occur. Inspectors no longer need to feel isolated on site. 

We all have needs, requirements, wants, and expectations. Needs are essential for life, to maintain certain standards, or essential for products and services, to fulfill the purpose for which they have been acquired. Requirements are what we request of others and may encompass our needs but often we don t fully realize what we need until after we have made our request. For example, now that we own a mobile phone we discover we really need hands-free operation when using the phone while driving a vehicle. Hence our requirements at the moment of sale may or may not express all our needs. Our requirements may include wants - what we would like to have but do not need nice to have but not essential. Expectations are implied needs or requirements. They have not been requested because we take them for granted - we regard them to be understood within our particular society as the accepted norm. They may be things to which we are accustomed, based on fashion, style, trends, or previous experience. Hence one expects sales staff to be polite and courteous, electronic products to be safe and reliable, policemen to be honest, etc. 

At present batteries worth more than 30 billion USD are produced every year and the demand is still increasing rapidly as more and more mobile electronic end electric devices ranging from mobile phones to electric vehicles are entering into our life. The various materials required to manufacture these batteries are mostly supplied by the chemical industry. Ten thousands of chemists, physicists and material scientists are focusing on the development of new materials for energy storage and conversion. As the performance of the battery system is in many cases a key issue deciding the market success of a cordless product there is in fact a kind of worldwide race for advanced batteries.

Longer uninterrupted operation of a number of smaller electronic devices (mobile phones, portable PCs, etc.) will require the ordinary batteries driving them to be replaced by power sources of higher capacity. 

In battery applications, new hthium ion batteries called lithium ion polymer batteries (or more simply but misleadingly, lithium polymer batteries) work with a full matrix of ionically conducting polymer, this polymer being present inside the porous electrodes and as a separator between the electrodes. They are offered in attractive flat shapes for mobile applications (mobile phones, notebooks). 

As an example of good choice of starting materials, NEC were interested in making wide use of biopolymers instead of petrochemically derived plastics and composites in their consumer electronics. There is a desire to use renewable materials to reduce reliance on non-renewables and to avoid the predicted rising cost of petrochemically derived materials. A range of biopolymers already exist, but they lack the performance required for products such as mobile phones, portable entertainment devices and mobile computers. 

In 2006 the material was used for the first commercial launch of mobile phones in lapan with a largely bioplastic case. 75% of the surface of the phone is bioplastic with only the screen and keypads made from conventional materials. The product has a good surface feel making it attractive to consumers, and meets all Japanese regulations for green purchasing and green electronic devices. 

Provide for easy repair, refurbishment or upgrading of the product. Click on casings allow users to change the style of their mobile phone without changing the core product. 

An LCD is a ubiquitous electronic display. Now, it is widely distributed among human daily life, like mobile phones, TV, and personal computers. The LCD has, however, a drawback, i.e., slower response than a plasma display or an electroluminescene display. Recently we have first succeeded in combination of a nanoparticle technology with the LCD technology, which realized fast response of the LCD [45,235,236]. Thus we have found a phenomenon, i.e., a frequency modulation of the LCD doped with metallic nanoparticles. Since the frequency modulation, or electro-optic property depends on the kind of metals, we have prepared AgPd bimetallic nanoparticles protected with a typical liquid crystal molecule, 4-cyano-4 -pentylbiphenyl (5CB) to investigate the electro-optic property [45,235,236]. 

Soft, silver white metal that melts in the hand (29.8 °C) and remains liquid up to 2204 °C (difference 2174 °C, suitable for special thermometers). Gallium is quite widespread, but always in small amounts in admixtures. Its "career" took off with the advent of semiconductors. Ga arsenide and Ga phosphide, which are preferential to silicon in some applications, have extensive uses in microchips, diodes, lasers, and microwaves. The element is found in every mobile phone and computer. Ga nitride (GaN) is used in UV LEDs (ultraviolet light-emitting diodes). In this manner, a curiosity was transformed into a high-tech speciality. 

Individual houses can have their own PV system for lighting and small appliances, such as radio and mobile phone charging. A village can benefit from a larger PV system, with a microgrid structure. 

Solar home systems. A solar home system is a PV system with capacity of 10-40 Wp (peak Watts). By 2007, Grameen Shakti had installed 100,000 solar home systems to power lights, motors, pumps, televisions, mobile phones, and computers in Bangladesh [1]. 

The report made by Yang et al. [23] determines the amount and composition of the e-waste flow in China (i.e. the quantity and the type of products that it includes). The document distinguishes among TVs, computers, mobile phones, air-conditioners, refrigerators, etc. Nevertheless, as aforementioned, this approach focuses on televisions (category 4) and computers (category 3).

The US Federal Communications Committee chose a frequency of 2.45 GHz for microwave ovens to ensure that they do not interfere with other equipment operated by microwaves, such as mobile phones. Therefore, we see that, contrary to popular belief, a frequency of 2.45 MHz is not a resonant frequency for molecules of water. 

The new generation of cordless phones transmit their text and verbal messages via microwaves, prompting persistent rumours that mobile phone can cause a user s ear to cook , much like a pie in a microwave oven. Too few studies have been performed to clarify, so the situation if still inconclusive. Certainly, the energy consumption of a mobile phone is tiny compared with that in an oven (a microwave oven operates with a power of about 200-1000 W, whereas a phone operates at a maximum energy of about 1 W - and the regulatory authorities are decreasing this maximum quite rapidly). 

While some studies suggest that these phones operating via microwaves are safe, others suggest that they are quite dangerous. In conclusion, whereas microwave ovens are definitively safe (if used correctly), many medical reports now suggest we try not to communicate via mobile phones too frequently.
